A SYSTEM AND METHOD FOR GENERATING SPATIAL INFORMATION USING BUILDING COORDINATE TRANSFORMATION OF DRAFT MAP DATA

摘要

PURPOSE: A space information construction system through the building coordinate conversion of draft map data and a method thereof are provided to support an improved intuition and a decision making by providing a more accurate and realistic virtual environment when constructing two-dimensional or three-dimensional information. CONSTITUTION: A data processing unit(300) receives at least one data between aerial photograph data or airborne laser surveying data from a data receiving unit(200). The data processing unit classifies the data into road data and building data. The data processing unit generates urban space information through an image processing about the classified road data and building data. An image display unit(500) outputs the generated two-dimensional or three-dimensional space information.
